主  題：Variable selection procedure from multiple testing

內(nèi)容簡(jiǎn)介：Summary. Variable selection plays an important role in statistical learning and scientific discoveries during the past ten years and multiple testing is a fundamental problem in statistical inference, also with wide applications in many scientific fields. This paper aims at figuring out a connection between adaptive lasso and multiple testing in the linear regression model, and aims at proposing a method based on the multiple testing to select variables and control the selecting error rate. Simulation studies show good performance of the proposed method on controlling the selecting error rate and achieving great powers under weak dependence.
Keywords: variable selection, multiple testing, adaptive lasso, false discovery
